Clinical Trials for Technetium Tc-99m Sulfur Colloid

RATIONALE: Diagnostic procedures, such as blue dye or imaging to identify sentinel lymph
nodes, may improve the ability to detect the extent of disease and help plan effective
surgery for removing breast tumors.
PURPOSE: Diagnostic trial to study the effectiveness of blue dye and an imaging procedure to
identify the sentinel lymph node under the arm in women with stage I or stage II breast
cancer.

Lymphoscintigraphy to Detect Early Metastases in Patients With Cancer of the Mouth or Throat

Completed

National Cancer Institute (NCI)

N/A

RATIONALE: New imaging procedures such as lymphoscintigraphy may improve the ability to
detect the spread of mouth and throat cancer to lymph nodes in the neck.
PURPOSE: Pilot study of lymphoscintigraphy followed by sentinel lymph node mapping and
sentinel lymph node biopsy to detect lymph node metastases in the neck in patients who have
mouth or throat cancer.

Lymphoscintigraphy to Detect Early Metastases in Patients With Cancer of the Mouth or Throat

Completed

New York University School of Medicine

N/A

RATIONALE: New imaging procedures such as lymphoscintigraphy may improve the ability to
detect the spread of mouth and throat cancer to lymph nodes in the neck.
PURPOSE: Pilot study of lymphoscintigraphy followed by sentinel lymph node mapping and
sentinel lymph node biopsy to detect lymph node metastases in the neck in patients who have
mouth or throat cancer.

RATIONALE: It is not yet known whether injecting technetium Tc 99m sulfur colloid and blue
dye near the tumor is more effective than injecting them near the nipple in identifying
sentinel lymph nodes in patients with stage I or stage II breast cancer.
PURPOSE: Randomized diagnostic trial to compare the effectiveness of injecting technetium Tc
99m sulfur colloid and blue dye near the tumor with that of injections around the nipple in
detecting sentinel lymph nodes in patients who have stage I or stage II breast cancer.
